Safe & Unsafe Foods
A mouse or rat’s diet should be built on a high-quality lab block or pellet food. This ensures they receive complete, balanced nutrition without the risk of deficiencies. I personally recommend brands like Mazuri and Oxbow Animal Health, which are widely trusted and formulated specifically for small animals.
Lab blocks should make up at least 90% of your pet’s diet.
The remaining 10% can be made up of fresh foods such as vegetables, leafy greens, grains, seeds, nuts, and small amounts of fruit. These additions are best used for enrichment, variety, and training treats—not as a replacement for their main diet.
I created this master list of safe and unsafe foods for mice and rats because it’s one of the most common questions I get. You can use it as a quick reference when deciding what to feed, what to avoid, and how to safely add variety to your pet’s diet. This will help you quickly determine what can be offered safely. Whether you’re building a foraging mix, choosing treats, or just asking “can they eat this?”, this list is designed to be a reliable, easy-to-use reference.
** A Note on the Order of These Items **
This list is organized based on how often these foods can be safely offered as treats, enrichment, or variety alongside a balanced lab block diet. It is not intended to represent a complete diet or be used to build one from scratch.
Creating a fully homemade diet for mice or rats requires advanced knowledge of their nutritional needs and careful balancing, and should only be done with proper research or guidance.
All foods listed here should make up no more than 10% of your pet’s total diet, with the remaining 90% coming from a high-quality lab block.
* New foods should always be introduced slowly to avoid digestive upset

Mice - 1-2 Teaspoons
Rats - 1-2 Tablespoons
Can be offered daily in rotation
Rats - 1-2 Tablespoons
Can be offered daily in rotation
Vegetables are the best fresh food to offer and should make up the majority of your pet’s fresh diet. They’re low in sugar and high in nutrients, making them safe to give daily in small portions. A typical serving is about 1–2 teaspoon-sized pieces per mouse (or a small handful for rats), rotated for variety. Focus on a mix of colors and types to provide balanced nutrition.
* Cooked Vegetables should be cooked without butter, oil, or fats and should have no salt, spices, or other seasonings added. For many vegetables, steaming or boiling is the best method of cooking. However, most veggies can be served to your mice raw and are more nutritional that way.

Lettuces and leafy greens are great for hydration and variety, but many are less nutrient-dense than other vegetables. They can be offered daily or several times per week in small amounts. A typical portion is a small leaf or a few bite-sized pieces per mouse. Rotate different greens to avoid overfeeding any one type, especially those high in oxalates.

Grains and other whole-food carbs provide energy but are already included in balanced lab blocks, so they should be offered as a supplement, not a staple. These can be given a few times per week in very small portions—about ½–1 teaspoon per mouse. Choose plain, unseasoned options and avoid anything heavily processed.

Herbs are best used for enrichment, flavor, and variety rather than as a primary food source. They are typically safe in small amounts and can be offered a few times per week or sprinkled lightly into foraging areas. A typical serving is a small pinch per mouse. Strong herbs should be used sparingly.

Protein Sources
Mice - Pea sized Portion
Rats - Bean sized to Small Bite (1-2 teaspoons depending on source)
1-2 Times per Week
Rats - Bean sized to Small Bite (1-2 teaspoons depending on source)
1-2 Times per Week
Protein is important for overall health but should be given in moderation, especially for adult mice and rats. Offer protein-rich foods 1–2 times per week in small amounts, such as a pea-sized portion per mouse. Too much protein can lead to long-term health issues, so keep servings controlled and occasional.

Seeds and nuts are very high in fat, making them ideal as treats or foraging rewards rather than regular food. These should be offered sparingly—about 2–3 times per week or less. A typical portion is 1–2 small seeds or a tiny nut piece per mouse. Overfeeding can quickly lead to weight gain.
